You cannot go below -0.5V for the inputs, since the board does not have an internal negative power supply, which would be necessary for that. If you have -0.8V pulses, the easiest is to use a passive inverter at the input to convert it to a 0.8V pulse.

Dear Evaluation Board Team,

 

currently I am facing the problem of digitizing pulses with an amplitude of -0.6V to -0.8V. As the dynamic range of the board is 1Vpp, this should be feasible. However, I do not know how to set in the software a correct range. I see only -0.5V/0.5V, and the two positive options. Normally I would use -0.5V/0.5V and give the thing an offset of 0.4V or so? Is this possible? Where can I set such a offset?

 

All the best,

Hans
